Abstract
The invention discloses a glycosylated protein-polyphenol Pickering emulsion and a preparation method thereof. The preparation method comprises the following steps: 1) preparation of a glycosylation reaction product; 2) preparation of a glycosylated protein-polyphenol complex; and 3) preparation of the glycosylated protein-polyphenol Pickering emulsion. The thermal stability of oil-water interfaceprotein is improved by Maillard reaction, and the stability of the Pickering emulsion is mainly provided by an interface particle layer, so that the purpose of improving acid heat stability of the emulsion is achieved; and meanwhile, epigallocatechin gallate is selected to effectively regulate the particle size of a glycosylated whey protein isolate, the prepared glycosylated protein-polyphenol complex with proper particle size can effectively inhibit the coalescence phenomenon among oil drops, emulsion drops show good homogeneity, the homogeneity of the emulsion drops is directly related tostorage stability, so that the purpose of improving the storage stability of the emulsion is achieved.
Description
technical field [0001] The invention belongs to the field of protein-based emulsion carriers, and more specifically relates to a glycosylated protein-polyphenol Pickering emulsion and a preparation method thereof. Background technique [0002] Pickering emulsions have received considerable attention in the pharmaceutical, cosmetic, and food industries due to their high stability, low toxicity, and controllable particle size. Pickering emulsions are stabilized by adsorbing particles at the oil-water interface and form a thin shell structure to prevent coalescence. The particles that stabilize Pickering emulsions are mainly derived from natural and synthetic materials. However, synthesizing materials involves toxic chemical agents and is restricted in the food and pharmaceutical industries. Therefore, natural, environmentally friendly edible material protein can be used as a good pickering stabilizer. Whey protein isolate (WPI) is a by-product of cheese manufacturing and ma...
